Quiz on Controlled Access Protocols

What is the main focus of today's lecture?

• Polling controlled access protocol

• Reservation controlled access protocol

• Random access protocols

• Channelization protocols

What is the first outcome of the session?

• Understanding random access protocols

• Learning about channelization protocols

• Knowing the various multiple access protocols

• Understanding the polling method

What analogy is used to explain the polling method?

• A library book borrowing

• A classroom setting

• A train reservation

• A restaurant reservation

What role does the master node play in the polling protocol?

• It sends data to all nodes

• It coordinates the transmission of data

• It receives data from all nodes

• It creates collisions

What is a significant drawback of the polling technique?

• It eliminates collisions

• It introduces polling delay

• It requires no master node

• It increases efficiency

What happens if the master node fails?

• Only some nodes can transmit

• The channel continues to operate

• The entire channel becomes inoperative

• All nodes can transmit freely

What are the two main functions associated with polling?

• Send and receive functions

• Poll and select functions

• Request and acknowledge functions

• Transmit and listen functions

How is the efficiency of the polling technique calculated?

• TT minus T poll

• T poll divided by TT

• TT divided by TT plus T poll

• TT plus T poll

What is the purpose of the reservation frame?

• To allow stations to make reservations

• To increase collisions

• To eliminate the need for a master node

• To send data immediately

How many reservation mini slots are there in a reservation frame?

• None for each station

• One for each station

• Five for each station

• Two for each station
